Prodrugs of NH-Acidic Compounds

ABSTRACT

The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

BACKGROUND OF THE INVENTION

(i) Field of the Invention

The present invention relates to prodrugs of lactam, amide, imide,sulfonamide, carbamate, urea, benzamide, and acylaniline containingpharmacophores.

(ii) Background of the Invention

Drug delivery systems are often critical for the safe and effectiveadministration of a biologically active agent. Perhaps the importance ofthese systems is best realized when patient compliance and consistentdosing are taken under consideration. For instance, reducing the dosingrequirement for a drug from four-times-a-day to a single dose per daywould have significant value in terms of ensuring patient compliance andoptimizing therapy.

Optimization of a drug's bioavailability has many potential benefits.For patient convenience and enhanced compliance it is generallyrecognized that less frequent dosing is desirable. By extending theperiod through which the drug is released, a longer duration of actionper dose is expected. This will then lead to an overall improvement ofdosing parameters such as taking a drug once a day where it haspreviously required four doses per day or dosing once a week or evenless frequently when daily dosing was previously required. Many drugsare presently dosed once per day, but not all of these drugs havepharmacokinetic properties that are suitable for dosing intervals ofexactly twenty-four hours. Extending the period through which thesedrugs are released would also be beneficial.

One of the fundamental considerations in drug therapy involves therelationship between blood levels and therapeutic activity. For mostdrugs, it is of primary importance that serum levels remain between aminimally effective concentration and a potentially toxic level. Inpharmacokinetic terms, the peaks and troughs of a drug's blood levelsideally fit well within the therapeutic window of serum concentrations.For certain therapeutic agents, this window is so narrow that dosageformulation becomes critical.

In an attempt to address the need for improved bioavailability, severaldrug release modulation technologies have been developed. For example,poorly soluble 5,5 diphenylimidazolidine-2,4-diones have beenderivatized into phosphate ester prodrugs to improve solubility. (Stellaet. al., U.S. Pat. No. 4,260,769, 1981). Enteric coatings have been usedas a protector of pharmaceuticals in the stomach and microencapsulatingactive agents using proteinaceous microspheres, liposomes orpolysaccharides have been effective in abating enzymatic degradation ofthe active agent. Enzyme inhibiting adjuvants have also been used toprevent enzymatic degradation.

A wide range of pharmaceutical formulations provide sustained releasethrough microencapsulation of the active agent in amides of dicarboxylicacids, modified amino acids or thermally condensed amino acids. Slowrelease rendering additives can also be intermixed with a large array ofactive agents in tablet formulations.

While microencapsulation and enteric coating technologies impartenhanced stability and time-release properties to active agentsubstances these technologies suffer from several shortcomings.Incorporation of the active agent is often dependent on diffusion intothe microencapsulating matrix, which may not be quantitative and maycomplicate dosage reproducibility. In addition, encapsulated drugs relyon diffusion out of the matrix or degradation of the matrix, or both,which is highly dependent on the chemical properties and watersolubility of the active agent. Conversely, water-soluble microspheresswell by an infinite degree and, unfortunately, may release the activeagent in bursts with limited active agent available for sustainedrelease. Furthermore, in some technologies, control of the degradationprocess required for active agent release is unreliable. For example,because an enterically coated active agent depends on pH to release theactive agent and pH and residence time varies, the release rate isdifficult to control.

Several implantable drug delivery systems have utilized polypeptideattachment to drugs. Additionally, other large polymeric carriersincorporating drugs into their matrices are used as implants for thegradual release of drug. Yet another technology combines the advantagesof covalent drug attachment with liposome formation where the activeingredient is attached to highly ordered lipid films.

However there is still a need for an active agent delivery system thatis able to deliver certain active agents which have been heretofore notformulated or difficult to formulate in a sustained release formulationfor release over a sustained period of time and which is convenient forpatient dosing.

There is a generally recognized need for sustained delivery of drugsthat reduces the daily dosing requirement and allows for controlled andsustained release of the parent drug and also avoids irregularities ofrelease and cumbersome formulations encountered with typical dissolutioncontrolled sustained release methods.

SUMMARY OF THE INVENTION

The present invention accomplishes this by extending the period duringwhich a lactam, amide, imide, sulfonamide, carbamate, urea, benzamide,acylaniline, and cyclic amide containing parent drug is released andabsorbed after administration to the patient and providing a longerduration of action per dose than the parent drug itself. In oneembodiment, the compounds suitable for use in the methods of theinvention are derivatives of lactam-, amide-, imide-, sulfonamide-,carbamate-, urea-, benzamide-, acylaniline-, and cyclic amide-containingparent drugs that are substituted at the amide nitrogen or oxygen atomwith labile aldehyde-linked prodrug moieties. Preferably, the prodrugmoieties are hydrophobic and reduce the polarity and solubility of theparent drug under physiological conditions.

In one embodiment, the invention provides a prodrug compound of FormulaI, II or III:

and the geometric isomers, enantiomers, diastereomers, racemates,pharmaceutically acceptable salts and solvates thereof;wherein A and B together with the —N(C═X)— or —N═C—X— or —S(O)₂—N— groupto which they are attached form a parent drug;

X is —S— or —O—;

R₁ is selected from —C(R_(A))(R_(B))—OR₂₀, —C(R_(A))(R_(B))—OC(O)OR₂₀,—C(R_(A))(R_(B))—OC(O)R₂₀, —C(R_(A))(R_(B))—OC(O)NR₂₀R₂₁,—(C(R_(A))(R_(B)))—OPO₃MY, —(C(R_(A))(R_(B)))—OP(O)(OR₂₀)(OR₂₁),—[C(R_(A))(R_(B))O]—R₂₀, —[C(R_(A))(R_(B))O]—C(O)OR₂₀,—[C(R_(A))(R_(B))O]—C(O)R₂₀, —[C(R_(A))(R_(B))O]_(z)—C(O)NR₂₀R₂₁,—[C(R_(A))(R_(B))O]_(z)—OPO₃MY, —[C(R_(A))(R_(B))O]_(z)—P(O)₂(OR₂₀)M and—[C(R_(A))(R_(B))O]_(z)—P(O)(OR₂₀)(OR₂₁);

-   -   wherein z is 2 or 3;    -   wherein each R_(A) and R_(B) is independently selected from        hydrogen, halogen, aliphatic, substituted aliphatic, aryl or        substituted aryl;    -   each R₂₀ and R₂₁ is independently selected from hydrogen,        aliphatic, substituted aliphatic, aryl or substituted aryl;    -   Y and M are the same or different and each is a monovalent        cation; or M and Y together is a divalent cation, and,    -   wherein when said parent drug contains a 5,5        diphenylimidazolidine-2,4-dione moiety of formula I, R₁ is other        than —CH(R_(A))OPO₃MY, CH(R_(A))OP(O)(OH)₂, or        —CH(R_(A))OC(O)R₂₀.

Chlorothiazide and hydrochlorothiazide compounds of formula III and inparticular table III are useful for the treatment of hypertension,congestive heart failure, osteoporosis, symptomatic edema peripheraledema, kidney stones, diabetes, nephrogenic diabetes insipidus,hypercalcaemia, Dent's disease and Meniere's disease. Compounds offormula III and table III provide sustained release of parent drugs bycleavage of the labile R₁ moiety. Compounds of formula III, for exampleIII-63 to III-71 are useful as prodrugs for the treatment of diabetes.

In another aspect of the invention a general method to convert compoundsof formula XLV with secondary amides to substituted tertiary amides isprovided (Scheme 1).

In addition to the reaction of aldehyde or ketone to compounds offormula XLV, other process for converting secondary lactam groups can beused. For example, alkylation followed by addition of sodium in inertsolvents, or addition of potassium hydroxide or sodium hydroxidefollowed by alkyl halide addition can be used. Microwave based syntheticprocedures can also be used to convert secondary lactams to substitutedtertiary lactam compounds of the instant application. (For a generalreview see March J. Advanced Organic Chemistry, Wiley, 1992; Inoue etal., Bull. Chem. Soc. Jpn., 58, 2721-2722, 1985; Mijin et al., J. Serb.Chem. Soc., 73(10) 945-950, 2008; Bogdal et al. Molecules, 1999, 4,333-337; U.S. Pat. No. 5,041,659).

The invention further relates the sustained delivery of a compound offormula XLV by the administration of a compound of formula I-III. Uponadministration of a compound of formula I-III, the labile R₁ moiety maybe cleaved off enzymatically, chemically or through first phasemetabolism giving a compound of formula XLV. Without being bound to anytheory, it is postulated that for some of the compounds of formulaI-III, the release of a compound of formula XLV upon cleavage of the R₁moiety results in a therapeutically active agent. For example suchactive ingredient can be aripiprazole, ziprasidone or bifeprunox. In oneembodiment, the sustained release comprises a therapeutically effectiveamount of a compound of formula XLV in the blood stream of the patientfor a period of at least about 8, preferably at least about 12, morepreferably at least about 24 and even more preferably at least about 36hours after administration of a compound of formula I-III. In oneembodiment, the compound of formula XLV is present in the blood streamof the patient for a period selected from: at least 48 hours, at least 4days, at least one week, and at least one month. In one embodiment, acompound of formula I-III is administered by injection.

The pharmaceutical compositions of this invention may be administeredorally, parenterally, by inhalation spray, topically, rectally, nasally,buccally, vaginally or via an implanted reservoir. In a preferredembodiment, administration is parenteral administration by injection.

The pharmaceutical compositions of this invention may contain anyconventional non-toxic pharmaceutically-acceptable carriers, adjuvantsor vehicles. In some cases, the pH of the formulation may be adjustedwith pharmaceutically acceptable acids, bases or buffers to enhance thestability of the formulated compound or its delivery form. The termparenteral as used herein includes subcutaneous, intracutaneous,intravenous, intramuscular, intraarticular, intraarterial,intrasynovial, intrasternal, intrathecal, intralesional and intracranialinjection or infusion techniques.

Liquid dosage forms for oral administration include pharmaceuticallyacceptable emulsions, microemulsions, solutions, suspensions, syrups andelixirs. In addition to the active compounds, the liquid dosage formsmay contain inert diluents commonly used in the art such as, forexample, water or other solvents, solubilizing agents and emulsifierssuch as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethylacetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butyleneglycol, dimethylformamide, oils (in particular, cottonseed, groundnut,corn, germ, olive, castor, and sesame oils), glycerol,tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid estersof sorbitan, and mixtures thereof. Besides inert diluents, the oralcompositions can also include adjuvants such as wetting agents,emulsifying and suspending agents, sweetening, flavoring, and perfumingagents.

Injectable preparations, for example, sterile injectable aqueous oroleaginous suspensions, may be formulated according to the known artusing suitable dispersing or wetting agents and suspending agents. Thesterile injectable preparation may also be a sterile injectablesuspension or emulsion, such as INTRALIPID®, LIPOSYN® or OMEGAVEN®, orsolution, in a nontoxic parenterally acceptable diluent or solvent, forexample, as a solution in 1,3-butanediol.

Additional sustained release in accordance with the invention may beaccomplished by the use of a liquid suspension of crystalline oramorphous material with poor water solubility. The rate of absorption ofthe drug then depends upon its rate of dissolution, which, in turn, maydepend upon crystal size and crystalline form. Alternatively, delayedabsorption of a parenterally administered drug form is accomplished bydissolving or suspending the drug in an oil vehicle. Injectable depotforms are made by forming microencapsule matrices of the drug inbiodegradable polymers such as polylactide-polyglycolide. Depending uponthe ratio of drug to polymer and the nature of the particular polymeremployed, the rate of drug release can be controlled. Examples of otherbiodegradable polymers include poly(orthoesters) and poly(anhydrides).Depot injectable formulations are also prepared by entrapping the drugin liposomes or microemulsions that are compatible with body tissues.

In one preferred embodiment, the formulation provides a sustainedrelease delivery system that is capable of minimizing the exposure ofthe prodrug to water. This can be accomplished by formulating theprodrug with a sustained release delivery system that is a polymericmatrix capable of minimizing the diffusion of water into the matrix.Suitable polymers comprising the matrix include polylactide (PLA)polymers and the lactide/glycolide (PLGA) co-polymers.

Alternatively, the sustained release delivery system may comprisepoly-anionic molecules or resins that are suitable for injection or oraldelivery. Suitable polyanionic molecules include cyclodextrins andpolysulfonates formulated to form a poorly soluble mass that minimizesexposure of the prodrug to water and from which the prodrug slowlyleaves.

In such solid dosage forms, the activecompound is mixed with at least one inert, pharmaceutically acceptableexcipient or carrier such as sodium citrate or dicalcium phosphateand/or: a) fillers or extenders such as starches, lactose, sucrose,glucose, mannitol, and silicic acid, b) binders such as, for example,carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone,sucrose, and acacia, c) humectants such as glycerol, d) disintegratingagents such as agar-agar, calcium carbonate, potato or tapioca starch,alginic acid, certain silicates, and sodium carbonate, e) solutionretarding agents such as paraffin, f) absorption accelerators such asquaternary ammonium compounds, g) wetting agents such as, for example,cetyl alcohol and glycerol monostearate, h) absorbents such as kaolinand bentonite clay, and i) lubricants such as talc, calcium stearate,magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate,and mixtures thereof. In the case of capsules, tablets and pills, thedosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers insoft and hard-filled gelatin capsules using such excipients as lactoseor milk sugar as well as high molecular weight polyethylene glycols andthe like.

The solid dosage forms of tablets, dragees, capsules, pills, andgranules can be prepared with coatings and shells such as entericcoatings and other coatings well known in the pharmaceutical formulatingart. They may optionally contain opacifying agents and can also be of acomposition that they release the active ingredient(s) only, orpreferentially, in a certain part of the intestinal tract, optionally,in a delayed manner. Examples of embedding compositions that can be usedinclude polymeric substances and waxes.

The ointments, pastes, creams and gels may contain, in addition to anactive compound of this invention, excipients such as animal andvegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulosederivatives, polyethylene glycols, silicones, bentonites, silicic acid,talc and zinc oxide, or mixtures thereof.

Powders and sprays can contain, in addition to the compounds of thisinvention, excipients such as lactose, talc, silicic acid, aluminumhydroxide, calcium silicates and polyamide powder, or mixtures of thesesubstances. Sprays can additionally contain customary propellants suchas chlorofluorohydrocarbons.

Transdermal patches have the added advantage of providing controlleddelivery of a compound to the body. Such dosage forms can be made bydissolving or dispensing the compound in the proper medium. Absorptionenhancers can also be used to increase the flux of the compound acrossthe skin. The rate can be controlled by either providing a ratecontrolling membrane or by dispersing the compound in a polymer matrixor gel.

For pulmonary delivery, a therapeutic composition of the invention isformulated and administered to the patient in solid or liquidparticulate form by direct administration e.g., inhalation into therespiratory system. Solid or liquid particulate forms of the activecompound prepared for practicing the present invention include particlesof respirable size: that is, particles of a size sufficiently small topass through the mouth and larynx upon inhalation and into the bronchiand alveoli of the lungs. Delivery of aerosolized therapeutics,particularly aerosolized antibiotics, is known in the art (see, forexample U.S. Pat. No. 5,767,068 to VanDevanter et al., U.S. Pat. No.5,508,269 to Smith et al., and WO 98/43650 by Montgomery, all of whichare incorporated herein by reference). A discussion of pulmonarydelivery of antibiotics is also found in U.S. Pat. No. 6,014,969,incorporated herein by reference.

By a “therapeutically effective amount” of a prodrug compound of theinvention is meant an amount of the compound which confers a therapeuticeffect on the treated subject, at a reasonable benefit/risk ratioapplicable to any medical treatment. The therapeutic effect may beobjective (i.e., measurable by some test or marker) or subjective (i.e.,subject gives an indication of or feels an effect).

In accordance with the invention, the therapeutically effective amountof a prodrug of the invention is typically based on the targettherapeutic amount of the parent drug. Information regarding dosing andfrequency of dosing is readily available for many parent drugs fromwhich the prodrugs of the invention are derived and the targettherapeutic amount can be calculated for each prodrug of the invention.In accordance with the invention, the same dose of a prodrug of theinvention provides a longer duration of therapeutic effect as comparedto the parent drug. Thus if a single dose of the parent drug provides 12hours of therapeutic effectiveness, a prodrug of that same parent drugin accordance with the invention that provides therapeutic effectivenessfor greater than 12 hours will be considered to achieve a “sustainedrelease”.

The precise dose of a prodrug of the invention depends upon severalfactors including the nature and dose of the parent drug and thechemical characteristics of the prodrug moiety linked to the parentdrug. Ultimately, the effective dose and dose frequency of a prodrug ofthe invention will be decided by the attending physician within thescope of sound medical judgment. The specific therapeutically effectivedose level and dose frequency for any particular patient will dependupon a variety of factors including the disorder being treated and theseverity of the disorder; the activity of the specific compoundemployed; the specific composition employed; the age, body weight,general health, sex and diet of the patient; the time of administration,route of administration, and rate of excretion of the specific compoundemployed; the duration of the treatment; drugs used in combination orcontemporaneously with the specific compound employed; and like factorswell known in the medical arts.

Example 68 Pharmacokinetic Evaluation in Rats Pharmacokinetic Evaluationof Prodrugs in Rats Following Intramuscular Injection

Animals:

Male Sprague-Dawley rats (Charles River Laboratories, Wilmington, Mass.)were obtained. Approximately 24 rats were used in each study. Rats wereapproximately 350-375 g at time of arrival. Rats were housed 2 per cagewith ad libitum chow and water. Environmental conditions in the housingroom: 64-67° F., 30% to 70% relative humidity, and 12:12-h light:darkcycle. All experiments were approved by the institutional animal careand use committee.

Pharmacokinetics Study:

Rats were dosed IM by means of a 25 gauge, ⅝ inch needle with 1 ccsyringe 0.3 mL suspension was withdrawn from the vial containing thetest compound (see Table E). The mouse was injected in the muscles ofthe hind limb after anesthesia with isoflourane. Blood samples werecollected via a lateral tail vein after brief anesthesia withIsoflurane. A 27½G needle and 1 cc syringe without an anticoagulant wasused for the blood collection. Approximately 350 μL of whole blood wascollected at each sampling time-point of 6 hours, 24 hours and 2, 5, 7,9, 12, 14, 21, 28, 35 days after administration. Once collected, wholeblood was immediately transferred to tubes containing K2 EDTA, inverted10-15 times and immediately placed on ice. The tubes were centrifugedfor 2 minutes at >14,000 g's (11500 RPMs using Eppendorf Centrifuge5417C, F45-30-11 rotor) at room temperature to separate plasma. Plasmasamples were transferred to labeled plain tubes (MICROTAINER®) andstored frozen at <−70° C.

Data Analysis:

Drug concentrations in plasma samples were analyzed by liquidchromatography-mass spectroscopy using appropriate parameters for eachcompound. Half-life, volume of distribution, clearance, maximalconcentration, and AUC were calculated by using WinNonlin Version 5.2software (Pharsight, St. Louis, Mo.).

Results and Discussion:

The Results are shown in Table J. As shown in Table J, each of thecompounds tested provides a plasma concentration that is extended ascompared to the parent drug when administered alone.

Example 70 Pharmacodynamic Studies Using an Amphetamine-InducedLocomotion Model

Introduction:

Prodrugs of the invention useful in the treatment of schizophrenia andbipolar disorder show predictive validity in rodent models ofhyperlocomotion. D-Amphetamine-induced locomotion is postulated to mimicthe dopaminergic hyperactivity which forms the basis for the “dopaminehypothesis” of schizophrenia. The AMPH-induced hyperactivity modelprovides a simple, initial screen of antipsychotic compound efficacy.See, Fell et al., Journal of Pharmacology and Experimental Therapeutics(2008) 326:209-217. Amphetamine induced hyperactivity was used to screenvarious doses of orally administered (PO) prodrug formulations ofaripiprazole to measure pharmacodynamic efficacy in an acutehyperlocomotion paradigm. The hypothesis of the study is that POadministration of aripiprazole prodrug formulations, which result inplasma concentrations of ˜100-200 ng/ml, will produce a significantattenuation of AMPH-induced locomotion.

General behavior and activity can be measured in experimental animals(typically rats and mice) in order to assess psychomotor stimulantproperties, anxiogenic/anxiolytic or sedative properties of a drug. Assuch, open-field studies can provide insight into the behavioral effectsof test compounds. Certain prodrugs of the present invention are usefulin the treatment of schizophrenia and bipolar disorder. Aripiprazole isa parent lactam containing drug from which some of the prodrugs of theinvention are derived that is useful in the treatment of schizophreniaand bipolar disorder. Such aripiprazole prodrugs of the invention showpredictive validity in rodent models of hyperlocomotion.D-Amphetamine-induced locomotion is postulated to mimic the dopaminergichyperactivity which forms the basis for the “dopamine hypothesis” ofschizophrenia. Likewise, glutamate NMDA receptor antagonist (MK-801,PCP, etc.) induced locomotion is postulated to mimic the NMDAhypoactivity hypothesis of schizophrenia (Fell et al., supra). Thesetests of drug-induced hyperactivity provide simple, initial screens ofantipsychotic compound efficacy. Amphetamine induced hyperactivity willbe used to screen various prodrugs of aripiprazole, administered PO inoil solutions, to measure pharmacodynamic efficacy. The results of theD-AMPH induced locomotion done in this study will be compared to thehistorical results of subcutaneous (S.C.) aripiprazole administration onD-AMPH. The hypothesis of the study is that PO exposure to aripiprazoleprodrugs, which results in aripiprazole concentrations of 100-200 ng/mlat locomotor testing, will display efficacy in in-vivo measures ofantipsychotic efficacy.

Materials:

Experimental Animals:

12, Sprague Dawley rats were purchased from Charles River Laboratory.The rats were approximately 90 days old, and weighed in the range of350-275 grams upon receipt from the supplier. One rat was placed in acage and allowed to acclimate for about 1 week. The rats were providedwith food and water ad libitum.

Dosing Solution of D-Amphetamine (D-AMPH):

D-AMPH was purchased from Sigma Aldrich. D-amphetamine HCl was preparedin 0.9% saline to a concentration of 1.5 mg/ml. D-Amphetamine was givenI.P. per body weight at a dose of 1 ml/kg (=1.5 mg/kg). Salt formcorrection was not used in accordance with historical literature.D-Amphetamine was prepared fresh from solid form 30 min. prior to eachtest period.

Behavior Box:

The behavior chambers were purchased from Med Associates, Inc. of St.Albans, Vt., Model ENV-515. Software for measuring animal movement isprovided with the behavior chamber by the supplier.

Methods:

Following 1 week habituation to the animal facility, the activityassessments commenced. The animals were initially acclimated to thebehavior box for about 15 minutes before they were removed from the boxand injected PO with 1.5 ml of an aripiprazole prodrug compound of theinvention, at concentrations which produce PK levels of 100-200 ng/mlapproximately 1 hour after administration. After an additional 15minutes the animals were placed back in the behavior box for anadditional 30 minute drug-baseline test session. The mice were thenadministered by IP injection, D-AMPH (1.5 mg/kg) followed by a 60 minuteexperimental behavioral measurement period. The parameters that weremeasured were a) total distance measured (primary measure), b) totalnumber of ambulatory moves (second measure), c) total number of verticalmoves (secondary measure) and d) time spent immobile (secondarymeasure).

Blood Sampling:

Tail vein blood was taken on experiment days immediately followinglocomotor activity measurements (2-hours post-prodrug administration)and again the following day a time-point corresponding to 22 hourspost-prodrug administration. Blood samples were collected via a lateraltail vein after anesthesia with Isoflurane. A 27½ G syringe without ananticoagulant was used for the blood collection, and the whole bloodtransferred to pre-chilled (wet ice) tubes containing K2 EDTA. 0.5 ml ofblood per animal was collected per time point. The tubes were inverted15-20 times and immediately returned to the wet ice until beingcentrifuged for 2 minutes ≧14,000 g to separate plasma. The plasmasamples prepared in this manner were transferred to labeled plain tubes(MICROTAINER®) and stored frozen at <−70° C.

Behavioral Data Acquisition:

Behavioral data was captured electronically by the software packageassociated with the behavior chambers. Data was transformed and analyzedvia GRAPHPAD PRISM® 5 software (GraphPad Software, Inc., La Jolla,Calif.). The data was analyzed using a 2-way repeated measures ANOVA.

Results and Discussion:

The results are shown in FIGS. 6 and 7. The results indicate that orallyadministered D-AMPH caused a significant increase in the total distancetraveled by the mice as compared to mice who were administered onlysaline. The results also indicate that aripiprazole prodrug compound 4of the invention significantly inhibited the increases in distancetraveled caused by D-AMPH. The inhibition of distance travelled bycompound 4 did not appear to be dose dependent. Likewise, aripiprazoleprodrug compounds 7 and 47 did appear to significantly inhibit increasesin distance traveled caused by D-AMPH at the higher dose of 20 mg. Thisdata indicates that in accordance with the invention, the prodrugcompounds are cleaved in vivo to release the parent drug (aripiprazolein this example) to provide the expected pharmacological effects on theanimal.
